A Study on the Heterogeneous Reaction of Trialkylsilyl Chlorides with Inorganic Salts and Monocarboxylates Catalysed by PEG400

The important and useful trialkylsilyl pseudohalides R 3 SiX, where X=NCS, NCO, N 3 or CN and R=methyl or ethyl, and trimethylsilyl monocarboxylates, where X=RCOO, were readily prepared in high yields by nucleophilic substitution of R 3 SiCl with X ions provided by NaX or KX at room temperature catalysed by PEG400 and zinc iodide. The reactions of trimethylsilyl chloride with some metal oxysalts were also studied for the first time.
